Publication number: 20140203961Abstract: A method is provided for analyzing debris events after a launch of a rocket-propelled vehicle. Radar and Doppler data of the launch of the rocket-powered vehicle is collected for a period of time. Atmospheric conditions are determined at the time of launch. A trajectory of the rocket-propelled vehicle is determined during ascent. The collected radar and Doppler data is aligned and calibrated. A first portion of the collected radar and Doppler data is processed with a first means for assessing and characterizing debris. In parallel with the first portion of the collected radar and Doppler data, a second portion of the collected radar and Doppler data is processed with a second means for assessing and characterizing debris.

Patent number: 8522082Abstract: Object-code instruction traces are employed to analyze selected instructions of a year-2000 (Y2K) remediated application program for possible remediation failure when confronted by a year-2000 date. The analysis includes directly identifying one or more instructions of the remediated application program that may fail. A remediation-failure-pattern descriptor is assigned to each examined instruction which is indicative of whether the remediated instruction may fail when confronted by a date in the year-2000 range. The analysis employs user-specifiable run-control values, as well as predetermined filter-specification values in comparing traces of each selected object-code instruction to predefined remediation-failure patterns.Type: GrantFiled: April 28, 2000Date of Patent: August 27, 2013Assignee: International Business Machines CorporationInventors: Brian B.

Patent number: 6336184Abstract: A central processing unit of an information handling system is provided with a Trap instruction to facilitate transfer of control from a user program to a trap program. A dispatchable unit control block (DUCT) of the CPU is loaded with the address of a trap control block, which in turn contains the addresses of a trap save area and a trap program. The user program is provided with Trap instructions at the desired transfer points. Upon decoding a Trap instruction in the user program, the CPU saves state information from the program status word (PSW), general registers and access registers in the designated trap save area, loads the address of the trap control block into a general register, and copies the address of the trap program into the instruction address field of the PSW to transfer control to the trap program. Upon completion of execution, the trap program may issue a Resume Program (RP) instruction to restore the previously saved state information to return control to the user program.Type: GrantFiled: August 14, 1998Date of Patent: January 1, 2002Assignee: International Business Machines CorporationInventors: Gregory A.
